Yes. Within Sydney, the ~most populous city of Australia, in readily accessible bushland under half an hour from major population centers, you can still easily locate many significant shell middens from aboriginal people presumably last used ~200+ years ago.

On that note, I once met someone who claimed to have found a piece of carved glass in the bushland peripheral to the city which would have dated from the period of initial contact between Europeans and aboriginals. He told me where it was found, in general terms, which is extremely inaccessible and thus it's still probably there - waiting for a rediscovery.

Further on that note, the main difference between hand grinding and initial machine grinding is a reliable rotary axis which generates a degree of symmetry and precision in the workpiece (due to the rotation about a fixed axis) not otherwise available to hand made tools. This is the general basis of all machining, ie. the use of a relatively precision ground reference plane or relative precision reference geometry to achieve precision work. Perhaps it can be said that it was the transition of an energy source to precise rotary motion (such as is used on pottery wheels and presumably very early lathes and grinding equipment) which sparked the industrial revolution and the modern era.

Amazing that the aboriginals of Australia had ~45,000 years (or ~1000 generations) of relatively stable presence but apparently never decided to invest in fixed machines for precision work. I guess this was because there is no evidence they ever had a wheel, which is a prerequisite, though anthropologically one might safely assume they frequently used round shape seedpods, stones or other naturally occurring elements to meet specific technical needs thus perhaps had no need to fashion artificially round elements. One may further suppose their seasonal lifestyles probably emphasised portability and reworkability in technological techniques over precision which probably offered very little in the way of benefit when you were, for example, spearing prey at relatively close range. After all, who wants to carry a machine hundreds of kilometers? Much better to build a new tool when you arrive.

Finally, I have a small ethnographic art collection focused on the Pacific. One of my better pieces is a very long hardwood paddle from the Sepik River of Papua New Guinea featuring immensely complex hand-carved scroll work and carved out of a single piece of solid timber. However, the shaft itself is clearly slightly off straight. Even in cases like this, where the inertial force of an entire boat and its contents would be presumably transferred through the paddle when navigating or stopping by poling off the river bed, extremely experienced and ancient traditional woodworking cultures would still clearly accept inconsistencies. One assumes that picking the right wood (knowing which tree to fell) and how to prepare, treat or store the timber was probably of greater functional utility to producing a useful and lasting tool than absolute geometrical accuracy.

Thus perhaps our current industrial obsession with precision machining is just largely irrelevant to a pre-metal age in which maximum forces were order of magnitudes lower.
